You can’t get away from the sea on the tiny island of Providence, between Jamaica and Colombia. Certainly it’s never out of Keyla’s mind after her father and his fishing boat disappear. They call the Caribbean “the sea of seven colours” here, and among the bright hues of tropical fish and corals are sinister tones. There are territorial disputes, rumours of drug-running, pirate legends; and all the complications of family and love, undercurrents of old hurts and the forging of new bonds as Keyla comes of age.
